975X Chipset
The Intel 975X chipset consists of the following devices:
• Intel 82975X Memory Controller Hub (MCH) with Direct Media Interface (DMI) interconnect
• One of the following:
• Intel 82975X Memory Controller Hub (MCH) with Direct Media Interface (DMI) interconnect
• One of the following:
⎯ Intel 82801GR I/O Controller Hub (ICH7-R) with DMI interconnect
⎯ Intel 82801GH I/O Controller Hub (ICH7-DH) with DMI interconnect
⎯ Intel 82801GH I/O Controller Hub (ICH7-DH) with DMI interconnect
The MCH is a centralized controller for the system bus, the memory bus, the PCI Express bus, and
the DMI interconnect. The ICH7 is a centralized controller for the board’s I/O paths. The BIOS
code is stored in the Serial Peripheral Interface (SPI) Flash device
